You can use the decorator extension point org.eclipse.ui.decorators. Add this to your plugin.xml:

<extension
      point="org.eclipse.ui.decorators">
   <decorator
         adaptable="true"
         class="MyDecoratorClass"
         id="some.id.for.decorator"
         label="Active Build Configuration Decorator"
         lightweight="true"
         location="BOTTOM_RIGHT"
         state="false">
      <enablement>
         <and>
            <objectClass
                  name="org.eclipse.core.resources.IResource">
            </objectClass>
            <or>
               <objectClass
                     name="org.eclipse.core.resources.IProject">
               </objectClass>
               <objectClass
                     name="org.eclipse.core.resources.IFile">
               </objectClass>
            </or>
         </and>
      </enablement>
   </decorator>
</extension>

Provide implementation in your MyDecoratorClass (or whatever name you choose) to check your project's active config and either adding text, or images. Perhaps have something like this: []

Whenever a user makes a modification that requires you to update the decorators so that the latest changes can be decorated you can use this:

// the resource whose properties changed and needs to be re-decorated
IResource resource = ...;

IDecoratorManager manager = PlatformUI.getWorkbench().getDecoratorManager();
IBaseLabelProvider decorator = manager.getBaseLabelProvider("id.of.my.decorator");
if (decorator != null)
    ((ILabelProviderListener) manager).labelProviderChanged(new LabelProviderChangedEvent(decorator, resource));
